Hi @ronfint ---- Thank you for the status update and as Mike has mentioned, my apologies for the slow response here.
Being as this behavior is continuing to manifest itself despite any of the troubleshooting tips given by other users and the Roon team members, I would strongly urge you to consider testing without the use of link aggregation. This is the one test that has not been performed yet and as stated, this would be a very good data point for us to have.
We understand that network troubleshooting can indeed be tedious, but the best approach we have found when handling these types of reports is to simplly use the process of elimination; removing complexity from the chain of communication and slowly adding the “links” back in to see where things break. Let us know how it goes.
